Chair with Urinal Device

ABSTRACT

A urinal chair includes a chair body and a urinal device. The chair body has a seat supporting frame defining an open seat area. The urinal device includes a top open drain pan, a cushion, a container and a cleaning device. The drain pan is supportably mounted upon the seat supporting frame of the chair body to fit in the open seat area of the chair body. The drain pan is slanted to drain toward a drainage aperture therein. The cushion is fit over the drain pan and defines a hole to permit drainage through the cushion to the drain pan. The container is disposed under the drain pan to collect liquid from the drain pan. Moreover, the cleaning device includes a cistern and a spout connected to the cistern. The spout is directed toward the drain pan for cleaning the drain pan with water stored in the cistern.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a urinal chair, and more particularly to such chair which may be used by chair ridden person without aid from any nurse or other attendant.

2. Description of the Related Art

Urination is a serious matter for spine-injured-patients, incontinent patients, elderly people and convalescents undergoing rehabilitation who must use wheel-chairs or special-purpose chairs for a long period of time in their daily lives. However, little consideration has been taken so far for any urine-collecting means useful for the above-mentioned patients and people in their wheel-chairs or special-purpose chairs.

U.S. Pat. No. 3,383,713 discloses a urinal chair that is specifically designated for senile patients who are continually wetting or urinating with little or no control in which the chair is provided with a comfortable cushion that is constructed to drain toward a center aperture in the cushion and in which the cushion is supported by a pan-like seat that is also provided with a drainage aperture to permit drainage through the drainage aperture and in which a container is affixed under the seat to collect and prevent the spread of urine. However, since the center aperture in the cushion is aligned with the drainage aperture in the pan-like seat, the pan-like seat would stink after a short time of use, which is quite unpleasant to the user.

SUMMARY OF THE INVENTION

It is an objective of this invention to provide a urinal chair for senile patients. It is a further object of this invention to provide a urinal chair that is provided with means to drain all urine into a sanitary container and maintain the urinal device as clean as feasible.

To achieve the foregoing objective, the urinal chair includes a chair body and a urinal device mounted on the chair body. The chair body has a seat supporting frame defining an open seat area. The urinal device generally includes a top open drain pan, a cushion, a container and a cleaning device. The drain pan is supportably mounted upon the seat supporting frame of the chair body to fit in the open seat area of the chair body. In addition, the drain pan is slanted to drain toward a drainage aperture therein. The cushion is fit over the drain pan and defines a through hole from top to bottom to permit drainage through the cushion to the drain pan. The container is affixed under the drain pan and has an opening in communication with the drainage aperture of the drain pan for collection of liquid from the drain pan. The cleaning device includes a cistern and at least one spout that is connected to the cistern and directed toward the drain pan.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF EMBODIMENTS

Referring to the drawings and initially to FIGS. 1-5, a urinal chair 100 is provided in accordance with the preferred embodiment of the present invention. As shown in FIG. 2, the urinal chair 100 includes a chair body 2 and a urinal device having a top open drain pan 1, a cushion 21, a container 3 and a cleaning device 4.

The chair body 2 has a seat supporting frame 23 that defines an open seat area 20 in which the drain pan 1 is fit. The seat supporting frame 23 is provided to support the drain pan 1 with its internal flange 231 upholding a top external flange 17 of the drain pan 1. In this embodiment, the chair body 2 is a wheel chair which includes four wheels mounted on legs 25 of the chair body 2.

As best seen in FIG. 3, the drain pan 1 is supportably mounted upon the seat supporting frame 23 of the chair body 2 and is fit in the open seat area 20 (FIG. 2) of the chair body 2. Moreover, the drain pan 1 is slanted to drain toward a drainage aperture 12 therein. Specifically, as shown in FIG. 2, the drain pan 1 has a front wall 18, a bottom wall 11 and two opposed side walls 19. The two side walls 19 are merged with the bottom wall 11. The bottom wall 11 is slanted downward and frontward toward the front wall 18 to have a higher rear side 111 and a lower front side 112. In particular, the bottom wall 11 has opposed side portions 16 slanted downward and frontward from the side walls 19 toward the front wall 18 to drain toward the drainage aperture 12 which is defined in a lower, front portion 15 of the bottom wall 11.

Referring to FIGS. 1 and 2, the cushion 21 is fit over the drain pan 1 and is held by the seat supporting frame 23 of the chair body 2. Moreover, the cushion 21 defines a through hole 22 from top to bottom to permit drainage through the cushion 21 to the drain pan 1, as depicted in FIG. 4. In particular, the through hole 22 of the cushion 21 is misaligned with the drainage aperture 12 in the bottom wall 11 of the drain pan 1. It is understood that the stinky smells can therefore be at least alleviated.

With reference to FIGS. 2 and 3, the container 3 is affixed under the drain pan 1 and has an opening 31 in communication with the drainage aperture 12 of the drain pan 1 for collection of liquid from the drain pan 1.

As shown in FIG. 2, the cleaning device 4 includes a cistern 41 and at least one spout 42. The cistern 41 is mounted on a back rest 27 of the chair body 2. The spout 42 is connected to the cistern 41 by a hose 43 and is directed toward the drain pan 1, as shown in FIG. 3, such that the drain pan 1 can be flushed when clean water comes out of the spout 42 from the cistern 41, as depicted in FIG. 5, and thereby ensuring that the drain pan 1 is maintained clean to keep the drain pan 1 from stinking.

Furthermore, the cleaning device 4 comprises a valve (not shown) disposed in the cistern 41 and a switch 5 disposed outside the cistern 41. The switch 5 is electrically coupled to the valve for controlling flow of liquid from the cistern 41 through the hose 43 and the spout 42 to the drain pan 1. Preferably, the switch 5 is mounted on an arm rest 26 of the chair body 2 to facilitate the operation of the cleaning device 4.

It should be noted that the urinal device of the present invention may be applied to various chair bodies. Referring to FIGS. 6 and 7, there are shown two alternate embodiments 200, 300. Each of the two embodiments 200, 300 is similar to the first embodiment 100, except that a car chair body 6 or a normal chair body 7 is provided in lieu of the aforementioned chair body 2 in FIG. 4. In the case where the chair body 7 has no arm rests, the switch 5 of the cleaning device 4 can be mounted to a lower side of a back rest of the chair body 7 instead, as depicted in FIG. 7.

It is to be understood that the disclosed embodiments are illustrative in nature and the invention is not to be limited to any one or more embodiments except as set forth in the following claims.
